A system for protecting an engine from damage due to vibration while the engine is not operating is provided. The system includes an engine having a crankshaft, at least one piston, at least one bearing, a lubricating fluid source, and a fluid pump associated therewith and a controller operationally connected to and configured to control the fluid pump. When the system is in a first mode, the controller is configured to control the fluid pump in a duty cycle to maintain a predetermined minimum fluid pressure of the lubricating fluid such that a lubricating fluid film is present between the at least one bearing and the crankshaft while the engine is not operating.
